I feel like making a list of all Anime and Manga I every watched and read, regardless of whether they are my favorites. If I can remember them all, that is. Here goes:
Detective Conan/Case Closed/Meitantei Conan [Anime] [Manga] - I watched the German localization as a kid, but now I'm only checking out the important episodes and chapters. After
the Bourbon arc I kind of lost interest but I'm still looking at this series every once in a while.
Doremi/Ojamajo Doremi [Anime] - I have not really watched through this series, but I remember some of the more important episodes.
Naruto [Anime] [Manga] - I watched most non-filler episodes of the regular anime, but stopped at some point in Shippuden. I did watch many of the important episodes after that, though.
Neon Genesis Evangelion [Anime] - I can't really remember this series well. I only started watching it because it was said to be one of Gainax Studio's finer works. The last few episodes really lost me. Heard the movie was good but never watched it.
Oruchuban Ebichu [Anime] -
Hanamaru Youchien / Hanamaru Kindergarten [Anime] - I don't really remember anything from this series but it was ok. I only watched it because I had been on a trip to watch some Gainax Studio Animes.
Tengen Toppa Gurren Lagann [Anime] - Pretty good Anime for what it is. I considered this my favorite for a long time.
One Piece [Anime] [Manga] - This series has a place in my heart and I'm always eagerly following new episodes and chapters. The Anime unfortunately suffers from slow pacing and the story-telling is quite clichéd.
The Dress Rosa arc sucked. But I appreciate the author foreshadowing and thinking through things and every single character has his own story and background.
Hajime no Ippo [Anime] [Manga] - There have been 3 Anime adaptions and the Manga is still ongoing after 1150 chapters. In the Manga, I hate the battles (which is strange for a Manga about boxing). The battles just get dragged out for like 15 chapters each time and I can't get invested in them. The plot points and funny/emotional moments outside of the battles I can really appreciate, though.
Especially in regard to Ippo and Kumi. Sooner or later, Ippo will have to choose between Kumi and boxing.
Dragon Ball [Anime] - Dragonball and Dragonball Z are the shit of my childhood! Dragon Ball GT I stopped watching midway through because it sucked. Dragon Ball Super, which is currently ongoing, I'm interested, especially in the current arc. But the animation quality sucks compared to Z and the "funny moments" sometimes kill the mood. The current few episodes (63~65) have been lacklustre, unfortunately. Overall, Dragon Ball Super is ok but could have been much better.
Super Kickers 2006 - Captain Tsubasa [Anime] - The only Tsubasa series I watched. Can't really remember how it ended. Was meh.
Megaman NT Warrior [Anime] - The only Megaman series I watched. Can't really remember how it ended. Was meh.
Hamtaro [Anime] - Have not really watched through this series, but I did catch a few episodes as a kid.
Ranma 1/2 [Anime] - This was also one of my favorites from my childhood. Unfortunately the German voice of Ranma had died and so the German adaption was canceled after 80 episodes or so. But I did continue with the English sub. Too bad the Anime didn't adapt all of the Manga.
The Promised Neverland [Manga] - This is an up and coming new Manga series that I rather coincidentally started reading. I really love it so far. Hoping this gets an Anime adaption later.
Golden Boy [Anime] -
Fist of the Northstar / Hokuto No Ken [Anime] [Manga] - Pretty good stuff. I marathoned through the Anime and then read the remaining non-adapted chapters. Was a pretty good experience.
Death Note [Anime] - The first half of this series was good, the second half was bland and meh. Overall, too much dialogue. I never really could get invested in this series as much as it seems everyone else could.
Sword Art Online [Anime] - Someone recommended this to me and I watched the first few episodes, but then stopped. Maybe I'll pick it up again later.
Panty & Stocking with Garterbelt [Anime] - This is filled with Awesome. Quite unique animation style. Sucks how it
ended in a cliffhanger
Spirited Away [ Movie] - Good movie
Pokémon [Anime] - I played Pokémon Yellow and watched most episodes from Gen 1. Everything after completely lost me.
Digimon [Anime] - Was also something I loved from my childhood. I watched everything except Tamers and Data Squad.
Kill la Kill [Anime] - I watched the first episode only... Somehow I didn't get hooked. Maybe will pick it up later.
